More than just a quickie ripoff of Westworld, the mainstream science fiction rage in the '70s, Sex World is a big sex picture, with a grand scope and richly developed characters. We follow a busload of people to a high-tech sex therapy center. Director Anthony Spinelli doesn't go for cheap thrills and laughs. He tries to get under the skin of the various people who go there to deal with their sexual hang ups and erotic fantasies. Sex problems concern frigid wives, dull marriages, orgies, guys who can't get hard and a woman who has a thing for Johnny Behind the Green Door Keys. As in Westworld, a team of technicians (headed by Annette Haven) supervise the boning. For all the effort, the show drags and takes itself way too seriously.
